Exploring Solutions for Space-Based Solar Power: Cost, Transmission, and Storage

In summary, the biggest hurdle for building a space based solar power system is the cost. While it is possible for space faring countries to come together and launch the necessary parts separately, the transmission of power from the satellite to Earth is also a major problem. The polar regions have the lowest atmospheric density, making them a potential location for the receiving base. However, there are concerns about the intensity of the laser beams or microwaves being used and the possibility of people being exposed to them. One solution could be to have helium balloons at a high altitude with receivers to minimize the distance the beam needs to travel through the atmosphere. However, storing the energy for a long time is another concern, as supercapacitors don't hold energy for

What is the biggest hurdle for building a space based solar power system?

is it the cost? All the space faring countries can come together and launch each part separately and then assemble them together just like the ISS right?

Is it the transmission of power from the satellite to Earth the problem?
Which part of the Earth has lowest atmospheric density?is it the polar regions? i don't know (i am thinking about laser beams)

Considering the satellite to be at a geostationary orbit .
Is it possible to have huge helium balloons along with receivers at a very high altitude to receive the laser beam(or microwaves ,which one is better?) so that the beam may not have travel too far in the atmosphere and lose it's intensity(is this a concern?). And there are also some concerns of people being exposed to high intensity microwaves if the receiving site is on the ground.
Can the energy be stored in some kind of supercapacitors attached to the balloons ,i know supercapacitors don't really hold on to the energy for long ,is there any other way to store the energy for a long time? so that the energy stored can be harvested once in few years or something?

Or is it economical to have the receiving base in places where population is very scarce?
Like some uninhabited islands or polar regions?

Are you asking literally just to create power for the surface? It costs like $10k/pound to put something in orbit. You could probably power a small town for the cost of putting enough panels in orbit to power a few houses.

this is actually a quite old topic .

Space based solar power

i was thinking of some possible solutions.
 

1. What is space-based solar power?

Space-based solar power (SBSP) is a method of collecting solar energy in space and transmitting it to Earth for use as electricity. This is done through the use of solar panels and microwave or laser beams to transmit the energy to receiving stations on Earth.

2. How does space-based solar power work?

SBSP works by using large solar panels to collect sunlight in space and convert it into electricity. This electricity is then transmitted to Earth using microwave or laser beams, which are received by receiving stations on the ground and then converted back into electricity for use.

3. What are the benefits of space-based solar power?

There are several potential benefits of SBSP, including the ability to collect solar energy 24/7 without being affected by weather conditions, the potential to provide renewable energy to remote or underdeveloped areas, and the ability to reduce our reliance on fossil fuels.

4. What are the challenges of space-based solar power?

One of the main challenges of SBSP is the high cost associated with launching and maintaining the necessary infrastructure in space. There are also concerns about the potential impact on the environment and the safety of transmitting large amounts of energy through beams to Earth.

5. Is space-based solar power currently being used?

While there have been several proposals and studies on SBSP, it is not currently being used as a widespread source of energy. However, there are ongoing research and development efforts to make SBSP a viable option in the future.
